2018-05-01spi: meson-spicc: Fix error handling in meson_spicc_probe()Alexey Khoroshilov1-3/+8
If devm_spi_register_master() fails in meson_spicc_probe(), spicc->core is left undisabled. The patch fixes that. Found by Linux Driver Verification project (linuxtesting.org).

2017-05-24spi: Add Meson SPICC driverNeil Armstrong1-0/+619
The SPICC hardware block on the Amlogic SoCs is Communication oriented and can do Full-Duplex 8- to 32-bit width SPI transfers up to 30MHz. The current driver only supportd the PIO transfer mode since the DMA seems broken on available hardware.
